Existing leadership theories and applied resources contain bountiful lists of recommended behaviors for leaders to employ, yet an integrated model that produces the most efficient set of leader behaviors does not currently exist. A standard, quantitative method to compare and contrast leader behaviors is needed to siphon utility from each resource, leading to an integrated and diversified set of optimal behaviors for leaders to consider. Leaders have limited time and need a reliable method to make informed behavioral decisions that consistently produce the most positive effects on the desired outcome. Unfortunately, leaders do not have the time to sift through the plethora of literary resources to uncover an optimal list of behavioral options. Leaders need to know what behavior to employ, when to employ it, the expected outcome, and the potential risk. Interestingly, these behavioral variables are also common to investors in the financial arena, where the principles of Modern Portfolio Theory (MPT) are often used to decipher the most optimal portfolio from a daunting list of investment options. The primary purpose of this study was to adopt some of the basic principles behind MPT in order to propose a similar quantitative Leader Behavior Portfolio Model, which determines an integrated and optimal set of effective leader behaviors. During this research, the proposed model was populated with archival performance data on over 5,000 cadets at the United States Military Academy. The outputs were then used to construct and administer surveys to 255 ROTC cadets in order to validate the model. The results of the survey response data were consistent with the outputs from the Leader Behavior Portfolio Model, showing strong support for adopting the principles of MPT to create an optimal set of leader behaviors.

Text in Afrikaans, abstract in Afrikaans and English / The development of leadership potential in adolescents cannot be approached in a haphazard manner. It ought to occur on the basis of a dynamic development model within a structured space. Such a model should not only prepare adolescents for their current leadership role, but also, and more particularly, its very nature should be more career-oriented. The question of what model will strive to equip adolescents with greater entrepreneurially-orientated leadership knowledge, therefore justifiably calls for closer investigation. In this study, an attempt has been made to find a suitable model to meet these needs. With this in mind, a study of the literature on the phenomenon of successful leadership was undertaken. Various relevant aspects that incorporate organisationally-structured management, were also examined. This enabled the researcher to develop a practice-oriented model from a study of the literature. In the implementation of the research design, use was made of qualitative research methods and techniques in order to collect and analyse relevant data. The study entailed 'action research' in which two independant groups were involved. For this purpose, the research results of the second cycle were concentrated on in order to reach findings and draw conclusions, and to make recommendations. This research ultimately revealed that adolescents have a deep need for entrepreneurially-oriented leadership development content. Individual participants also derived significant benefits from the implementation of the model. Owing to the success achieved with this research study, the management team of the school involved has decided to establish a full-time entrepreneurship centre for its pupils. This study can therefore be regarded as a contribution towards meeting the need for similar models in South African schools, in a practical and viable way. / Die ontwikkeling van adolessente se leierspotensiaal is nie iets wat lukraak aangepak kan word nie. Dit behoort aan die hand van 'n dinamiese ontwikkelingsmodel binne 'n gestruktureerde ruimte te geskied. Sodanige model behoort adolessente nie alleen vir hul huidige leierskaprol voor te berei nie, maar behoort in besonder ook 'n meer beroepsgerigte karakter te openbaar. Daar kan dus tereg gevra word hoe die model behoort te lyk wat daarna streef om adolessente met groter entrepreneursgerigte leierskapskennis toe te rus. In hierdie studie is gepoog om vas te stel of 'n geskikte model gevind kan word wat aan bogenoemde behoefte voldoen. Met die oog hierop, is 'n literatuurstudie oor die verskynsel van suksesvolle leierskap onderneem. Daarbenewens is verskeie toepaslike aspekte waarbinne die bestuurswese hom in 'n organisatoriese struktuur vergestalt, ook van nader beskou. Dit het die navorser in staat gestel om 'n praktykgerigte model vanuit 'n literatuurstudie te ontwikkel. Tydens die implementering van die navorsingsontwerp, is van kwalitatiewe navorsingsmetodes en -tegnieke gebruik gemaak om relevante data in te samel en te analiseer. Die studie het voorts die vorm van aksienavorsing aangeneem waarby twee onafhanklike groepe betrek is. Vir die doeleindes is daar op die navorsingsresultate van die tweede siklus gekonsentreer om bevindinge, gevolgtrekkings en aanbevelings te maak. Hierdie navorsing het uiteindelik getoon dat adolessente 'n groot behoefte aan entrepreneursgerigte leierontwikkelingsinhoude toon, terwyl individuele deelnemers baie baat by die implementering van sodanige model gevind het. Op grond van die sukses wat met hierdie navorsingstudie behaal is, het die bestuurspan van die betrokke skool besluit om 'n voltydse entrepreneurskapsentrum vir sy leerlinge tot stand te bring. Hierdie studie kan derhalwe beskou word as 'n bydrae om die behoefte aan soortgelyke modelle in Suid-Afrikaanse skole op 'n prakties-uitvoerbare wyse te vervul. / Psychology of Education / D. Ed.
